J. N; AYRES', OF STAMFORD, CONNECTICUT, ASSIGNOR TO THE STILLWATER COMPANY, OF SAME PLACE.

Letters Patent No. 91,592, dated .Time 22, 1869.

m IMPROVED MACHINE FOR BENDING WIRE FCR RAKE-TEETH.

The Schedule referred 4to in these Letters Patent and making part Of the Same.

A plate, C, having a series of different-sized 'apertures, is tit-ted across the plate B, so that one aperture will be in line with the groove.

This plateC is at the end f the rounded portion of the plate, Where the same joins the straight part.-

The wire is fitted through the hole of the plate C, and is then bent over the rounded part of the plate A, 'whereby it is straightened.

While its end is thus bent, the coil of wire is, or may be, supported on pins a a, that project from the side of the plate A.

The straightened portion of the wire is fed along in the horizontal groove until it strikes a stop or gauge, b, and is then cut off by suitable knives or shears.

To all whom, it may concern:

Be it known that LJ. N. AYRES, of Stamford, in the county otFaix-tield, and State of Connecticut, have invented an Improved Wire-Bending Machine; and I do hereby declare that the following is a full, clear, and exact description thereof, Awhich nwill Yenable others skilled in the art to make and use the same, reference being had to the accompanying drawing, forming part of this specification.

The drawing represents a perspective view of my improved wire-bending machine.

This invention relates to a new apparatus for straightening wire which is vto be used for the teeth of horse hay-rakes, and for`` other purposes, and has for its object to relieve the wire from the strain to which it is subject-ed in' the ordinary machines now in use. Heretofore, the Wire was usually bent between rollers or other devices, by which it was so strained that the elasticity was taken out of it, so that it became comparatively useless for the purposes to which it was to be applied.

The present invention consists in the application of a plate, having a grooved curved edge, on which the wire is bent, to remove the roundness, and which carries a perforated plate or stop, by which the Wire is held While being` bent.

`, A, in the drawing, represents a plate,rnade of metal,

Wood, or other suitable material. Itis set up vertically on a suit-able frame, B, and has its upper horizontal edge grooved, and 4rounded o" to one side.

It will be seen that the wire, while thus passed through the plate C, is not in the least strained, and conveniently turned.

Having thus described my invention,

I Vclaim as new, and desire to secure by Letters Patent- The construction and arrangement of the grooved former A, perforated holdingplate C, and supports B BY in the manner described, and for the purpose set forth.
